SAWIN G-MACHIN E Patented April 28, 1908.

Application filed February 11, 1907. Serial No. 356,869.

To all whom it may concern:

Be it known that I, Go'rTLIEB BINDER, citizen of the United States,residing at Louisville, in the county of Jefferson, State of Kentucky,have invented certain new and useful Improvements in Sawing-Machines, ofwhich the following is a specification, reference being had therein tothe accompanying drawing.

This invention relates to a metal sawing machine, and articularly toaconstruction where a circu ar saw is fed relative to the work.

The invention has for an object to provide a novel and improvedconstruction of driving means for the saw, and for the casing containingthe same by which these parts may be positively driven by a beltconnection or fed by a hand operated device, while the driving may beaccomplished at different speeds.

A further object of the invention is to provide a novel and improvedconstruction of clamp for retaining the work in proper position for theaction of the saw which is fed relatively toward and from the same.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

In the drawings:Figure 1 is an elevation of the invention with parts insection; Fig. 2 is a top plan thereof; Fig. 3 is a side elevation Fig. 4is a front view of the clamp; Fig. 5 is an enlarged vertical sectionthrough the shifting device for the driving connections, and Fig. 6 isan enlarged horizontal section through the clutch mechanism for thedriving pulley.

Like numerals refer to like parts in the several views of the drawings.

The numeral 1 designates the base or bed of the machine which may be ofany desired construction or configuration and provided with the feedscrew 2 pivotally mounted to rotate therein. Upon the upper face of thebed the casing 3 is mounted to travel or slide longitudinally andprovided with depending bearing lugs 4 intermediate of which the drivingworm gear 5 is disposed and threaded upon the shaft 2. This worm gearmeshes with the worm 6 secured to the driving shaft 7 by a spline or-key8 so as to rotate therewith. The shaft 7 is mounted in the casing 3 bymeans of bearing sleeves 9 and the end 10 of the shaft 7 isextendedbeyond the casing and there provided with'a speed gear 11loosely mounted thereon and provided with a key way 12 adapted tocooperate with the key 13 carried by the push rod 14 which is providedwith an operating handle 15. This key travels in the slot 16 formed inthe end 10 of the shaft 7. The rod 14 also carries a gear key 17 at itsinner end which is adapted to travel in the slot through the shaft 7 asthe rod is disposed in the recess 18 within said shaft. This key 17 isadapted to engage and enter a channel or way 19 in the driving pinion 20which is geared to the saw driving mechanism as hereinafter described.The casing 3 is secured against vertical move ment on the base 1 bymeans of the lugs 21 extended therefrom at opposite sides embracing theribs 22 on the bed. When the rod 14 is withdrawn, as shown in Fig. 5,the parts are connected to be driven from the saw connections throughthe pinion 20 and the worm 6 so that the casing is actuated on the feedscrew. When this rod is pressed inward the keys thereof disconnect thepinion 20 and connect the low speed gear 11 so that the feed screw isfree to be driven by a gear connection which may comprise the gear wheel38. When it is desired to drive by the hand connection, the wheel 23splined on the feed screw, and provided with a clutch member iswithdrawn from the fixed cooperating clutch member 24 on the bed andwhen the wheel is held in clutched position the parts may be driven fromthe saw mechanism.

The circular saw 25 is mounted upon the shaft 26 in the casing orcarriage 3 and is adapted to be driven from the power pulley 27 disposedupon the shaft 28. This shaft is provided with an elongated pinion 29which meshes with the gear 30 disposed upon the V shaft 31 which shaftalso carries the pinion 32 meshing with the cooperating gear 33 upon thesaw shaft 26, and the shaft 31 also carries the low speed gear 38] Thepower shaft 28 may be provided with the automatic stop comprising theordinary spring operated clutch from which the operating lever 35 eX-tends and adapted to be operated by engagement with a fixed part. Forthe purpose of driving the casing or carriage from the power shaft ofthe saw, a pinion 36 is disposed between and intermeshes with thedriving pinion 29 and the gear 20 on the worm shaft, as

' shown in Figs. 1 and 2 and provides the high I the worm thereon.

speed. Any suitable oil feeding device may be disposed adjacent the saw,for instance, as shown at 37 in Fig. 1'.

The work holder herein shown provides a novel and improved constructionfor supporting the work in any desired position for action by the sawand to allow the maximum length of cut thereby. It comprises the frame40 mounted upon the base 1 and having gibs 41 to retain it in positionand against vertical movement thereon. This frame is provided at oneside with a table or platform 42 to engage and operate the clutch lever35, and with the clamping plate 43 which is preferably formed with acorrugated surface. The cooperating plate 44 is swiveled at 49 upon thelower end of the screw 45 and provided at each end with clampingsurfaces 46 disposed opposite the plate 44, as shown in Fig. 4. Thisscrew is mounted in the neck 47 and provided with the operating handle48 so as to be adjusted into contact with the work.

The casing 3 is provided with inclined faces 50 opposite the collar 51of the clutch operating lever 35 which is loosely mounted 1 upon theshaft 28. This collar is provided with lugs 52 bearing upon the faces50, and the hub 53 of the pulley 27 is loosely mounted on the shaft andheld in sliding contact with the collar by the spring 54 bearing againstthe sleeve 55 secured at the outer end of the shaft. The hub 53 isformed with a clutch member 56 upon its outer face and the sleeve withthe cooperating member 57. With the parts in the position shown in Figs.2 and 6 the inclined faces have forced the pulley hub into clutchedcontact with the sleeve secured to the shaft. When the oper ating leveris raised by any means the lugs thereon pass down the inclined. faces ofthe casing and permit the spring to force the pulley hub out of clutchedcontact with the sleeve.

In the operation of the invention, with the key rod in the positionshown in Fig. 5 the saw will be continuously driven and the casing orcarriage fed toward the work holder at high speed as the pinion on theworm shaft being keyed thereto drives the worm and its gear so that thelatter travels upon the feed screw of the base. The feed through thistrain of gears is at a relatively high speed essential for the metalsawing operation, and at this time the hand wheel keyed upon the feedscrew is slipped into engagement with the fixed clutch member whichholds the screw against rotation to permit the feed of When it isdesired to accomplish this feed at a less speed the key rod is pushedinward disconnecting the high speed pinion on the worm shaft and keyingthe low speed gear thereto which is driven by its associate carried uponthe shaft 31 of the saw driving train, and provision is thus made forhigh or low speed of the parts whendriven from the power pulley, and ifthis pulley be unclutched the feed can be accomplished. by hand bysimply withdrawing the hand wheel from the fixed clutch member androtating the feed screw thereby. It will be seen that in the travel ofthe casing or carriage the operating lever for the automatic stop clutchengages the shelf or projection at one side of the work holder and isforced upward into the dotted line position shown in Fig. 3 so that theusual spring construction of the clutch releases the driving connectionand stops the operation of these parts. The construction of the clampprovides means for supporting the work in such position as' to securethe longest possible length of cut by the saw and the swiveled top platepermits the work to be held at an angle. It will also be observed thatthe driving train for the saw-insures a positive drive and feed of thesaw carriage which prevents breakage of the saw and insures uniformityand accuracy of the cut essential. in a metal working tool.
